Who we are.
Medina Diamonds is a B2B wholesaler of certified CVD lab-grown diamonds and melee. We serve jewelers, designers and retailers with a carefully curated inventory of round, melee and fancy-shape stones — all backed by IGI, one of the industry's most trusted grading labs.
To make wholesale sourcing simple, honest, and fast.
We built Medina Diamonds around one idea: the trade deserves a supplier that treats wholesale like a partnership, not a transaction. That means deep live inventory, transparent pricing, and a team that picks up the phone.
Every diamond we supply is independently certified by IGI. No exceptions. We work exclusively with registered businesses in the jewelry industry, so you can build confidently on top of what we deliver.
